- * No-locale-support setlocale() added.
+/* Nov. 1, 2002
+ *
+ * Reworked setlocale() return values and locale arg processing to
+ * be more like glibc. Applications expecting to be able to
+ * query locale settings should now work... at the cost of almost
+ * doubling the size of the setlocale object code.
+ * Fixed a bug in the internal fixed-size-string locale specifier code.
+ *
+ * Dec 20, 2002
+ *
+ * Added in collation support and updated stub nl_langinfo.
